Campanula portenschlagiana aka Adria Bellflower

Campanula portenschlagiana, also known as wall bellflower, Dalmatian bellflower, Adria bellflower, or Campanula muralis, is a species of flowering plant in the family Campanulaceae. It is native to the Dalmatian Mountains of Croatia and Herzegovina in southern Europe. This plant is a vigorous, low-growing, mound-forming evergreen perennial that can spread rapidly as a ground cover to as much as 24" wide. It has small, triangular, medium to dark green leaves with toothed margins and bell to cup-shaped purple flowers that cover the plant in late spring to late summer, sometimes early fall. Another popular houseplant, the Peach-Leaf Bellflower, needs regular watering to thrive and does best in long-lasting, direct light less than 1 foot from a window. This plant likes soil that is well-draining and doesn't usually need added fertilizers if you repot each time it doubles in size. The genus name Campanula comes from the Latin word campana, which means bell, in reference to the bell-shaped flowers.
